To be fair, classic Windows had its share of poor UI choices. Remember those days of a system tray with 25 icons in it?
It's no different than building up the option flags in a bash or powershell one liner. It's the direct graphical translation even.
The Win11 taskbar is like having only a systray with 25 icons in it.
It is poor design by having that be the form of which quick access to settings is provided. The tray icon paradigm simply invites clutter.
The taskbar icons are added by programs that are running. Disabling autorun for them prevents them from starting, and therefore the icons from showing up. I'd say 90% of the time disabling autorun for the companion program doesn't break any functionality.
I used to repeat that line too, 25 years ago when I was still on Windows 3.x, but it's gotten a little old since then.
